JSI External Camera Part support for ReStock mod

[StoneBlue]

RPM External Camera part uses stock model/texture. Fails to load when ReStock is installed, due to ReStock disabling Squad models/textures.

ReStock has implemented a simple workaround for mods that depend on stock models/textures.
Blowfish wrote a simple plugin that can blacklist/whitelist its disabling of Squad files.

For whitelisting (keeping Squad files), a simple text file needs to be created with the extension ".restockwhitelist", simply containing the folder URL for the Squad files that need to be loaded, and not disabled by ReStock.

The fix is so simple, that I didnt think it was worth a PR...just one line. Sorry.
Here is the contents of said file:

Squad/Parts/Utility/linearRCS/

Then save it with filename of JSI.restockwhitelist
Save in a location with other RPM support patches, and done.
That will keep ReStock from disabling loading of that folder which has the model and texture files that the external camera needs.
